To all whom t may concern:

Be it known that I, JOSEPH M. KAYE, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Keyless Locks, of which the following is a specification.

My invention relates to an improvement in the class of keyless locks used on handbags, brief-cases, toilet cases and boxes, reticules, and the like receptacles. The lock referred to comprises a latch-member to enter an opening in the casing of the companion member, which is provided with a bolt reciprocable relative to the opening when the two members are in operative relation, to enable the latch, when projecting through the hole, to be releasably engaged by the bolt, which is ordinarily spring-pressed to resiliently retain it in its locking position.

The primary object ofthe present mprovement is to prevent the bolt from accidentally releasing the latch; and my invention consists in adjustable means for that purpose.

In the accompanying drawing- Figure l is a face view of the lock provided with my improvement in its preferred form and illustrated in exaggerated dimensions;

Figure 2 is a rear view of the same, but with parts broken away to show details;

Figure 8 is an enlarged section on line 3 3 of either of Figs. l or 2;

Figure t is an enlarged section on line 4 4 of either of Figs. 2 or 3.

The latch-member 7 is adapted to be secured, as usual, centrally on the outer face of the edge portion of one of the jaws or the closure-flap of a receptacle equipped with a keyless lock of the class referred to. As shown, this member comprises a rectangular plate S provided with an edge flange 8a and containing a longitudinal slot 8b, at the ends of which those of a pin 9 are removably confined in bearings 9a on the inner or rear face of the plate; and a latch 10, provided with a hooklike tongue l0n on its free end-portion, has a sleeve 10b formed on its opposite end to pivotally surround the pin 9 about a helical spring l1 thereon tending to raise or open the latch. The latch-member may be of any suitable construction, that shown being well-known and in common use.

The bolt-member 12, as represented in the drawings and also of well-known general construction, is adapted to be secured on a receptacle with which a keyless lock is to be used, in position to cooperate with the latchmember. It comprises a rectangular plate 13, shown to be of larger dimensions than the plate 8 of the latch-member and providedv with an edge-flange 13a and a central keeper-hole la to receive the tongue lOa of the latch l0. In the back of the plate 13 is rigidly secured, as by screws l5 having washers l5a applied to their inner ends to lie within the confines of the fianged plate 13 or casing, an end-hanged plate 16, through the flanges of which the screws are passed, the plate thus forming a guiding space for housing the bolt 17 to adapt it to be reciprocated relative to the hole la. The bolt is on a stem 18 passing through a vertical slot 13b in the plate 13 and the inner end portion of the bolt and terminating as shown in Fig. 2, in an arch-shaped opening loa in the housingplate lo. The stem 18, which is rotatable in its bearing in the bolt for the feature of my improvement in its preferred embodiment, hereinafter described, is secured by a nut 19 and provided on its outer end with a handle of any suitable form, that shown being a knob 20, or button carrying a pivotally suspended loop 20": The bolt is spring-pressed bv a spring 17 confined against it to tend to hold it resiliently in its normal position with its advance edge extending part way across the hole 14.

0n the inner end of the stem 1S is secured to rotate with it a stop-finger 21, which is preferably in the form of a T to provide arms 21l (Fig. 2) of slightly springy quality and having depressions formed in their' end-portions to produce protuberances 2lb for entering recesses 2lc in the adjacent surface of the bolt, thereby to frictionally retain the finger in either of its two boltobstructing and non-obstructing positions.

A receptacle provided with a keyless lock of the kind referred to is locked, when closed, by the latch-tongue 10a on the one member of the lock projecting through the hole 14 in the other member thereof and being engaged by the bolt 17. For the unlocking purpose, the handle 2O is manipulated to withdraw the bolt from the latch, thereby releasing the latter. However', in this class of lock the bolt is liable to be accidentally withdrawn and thus unlock the receptacle with the result ot opening the latter and leaving it open unconsciously to the person carrying it, in which condition the receptacle may be surreptitiously rifled, or the contents may tall out and be lost. With my improvement in such a lock, accidental opening ot the receptacle may be avoided, since after locking, by turning the handle and With it the stem halfway around, the finger 2l Will abut against the lower edge of the recess 16a in the bolt-housing plate 16 and act as a stop against retraction of the bolt from engagement With the latch-tongue 10a. For there after unlocking the receptacle, the handle is turned, preferably another halfway around, to disengage the linger from its stopping position, whereupon the handle may be ma nipulated to retract the bolt for releasing the latch. In either position of the stop-finger, it Will be rict-ionally held by engagement of the projections 2lb with the recesses 21C.

`I realize that considerable variation is possible in the details of the construction herein shown, and I do not intend to limit myself thereto, except as pointed out in the appended claims, in which it is my intention to claim all the novelty inherent in the device as broadly as is permitted by the state t the art. I claim: l. In a keyless lock, in combination with a latch-'equipped member, a bolt-containing member comprising a casing provided with an opening to receive the latch tongue and containing a bolt-housing having an opening in its inner end, a boit guidingly confined in saidhousino'rto be reciprocated relative to said opening, a stem passing rotatably through the casing and bolt and reciprocable with'tlie latter, a handle on the outer end of the stein and a stop-iinger on the inner end thereotand rotatable therewithin said housing-'opening to engage the base thereof in the locking position of the bolt to obstruct retraction of the bolt' from said position. y

2. In a keyless lock, in combination with a latclrcquipped member, a bolt-containing member comprising a casing providedavith an opening to receive the latch tongue and containing a bolt-housing` having an opening in its inner end, a bolt guidingly confined in said housing to be recipiocated relative to said opening, a stem passing rotatably through the casing and bolt and reciprocable with the latter, a handle on 'the outer end ot the stem, and a stop-finger on the inner end thereof and rotatable therewith in said housing-opening to engage the base thereof in the locking position of the bolt to obstruct retraction oi the bolt from said position,

said tongue having arms provided With pr'o- Y )ections to enter corresponding recesses in the bolt for frictionally retaining the stopiingcr in adjusted position.
